CONNECTOR FOR ELECTRICAL CONDUCTORS.

Specification of Letters-Patent.

Patented Feb. 27, 1 906.

Application led pril 3, 1905. Serial No. 253,390.

To a/ZZ whom t may concern:

Be it known that I, FREDERICK J. TROLL, a citizen of the United States, residing at Bal timore, in the State of Maryland, have invented new and useful Improvements in Connectors for Electrical Conductors, of which the following is a specification.

This invention relates to connectors for electrical conductors.

' It has for its object to improve that type of connectors which is formed by two parallel sleeves, preferably madeof copper or other soft conducting material and adapted to receive the ends of two Wires or conductors to be connected, the connector and the wires being twisted together.

vIn this type of connector the workmanA strips the insulating material om the inclosed conductor with'a knife, and lin most if not all instances the soft conductor is cut or injured by the knife at the 'point where the conductor leaves the insulation. The conductor, on being fitted into the sleeve until the ends of the insulation engage the ends of the sleeve, brings the injured part of the conductor to a position where. no support is provided for it. If the two connected conductors are subjected to much handlin I, the conductors will very soon v.break at t is point, making a newconnection and a new connector necessary.

In my invention I provide enlarged eX- tensions at each end of the connector adapted to receive al portion of the insulation on each conductor. The enlarged extensions are of soft material, which permits of their being clamped upon the insulation and thereby forming an additional securing means for the wires. Further, they are so disposed that the conductors lead from the connector in alinement with one another.

Other objects and advantages will appear from the following description and will be more (particularly pointed out in the appende claims.

In the drawings, Figure 1 is an enlarged plan view of, one embodiment of my invention. Fig. 2 is a horizontal section of thc embodiment shown in Fig. 1. Fig. 3 is a side elevation. Fig. 4 is a plan of the same embodiment with conductors fitted therein;

and Figs. 5, 6, and 7 are respectively a planfa horizontal' section, anda side elevation, of another embodiment of my invention.

Referring more particularly to the drawings, 1 and 2 indicate a pair of connected parcuringmeans for the conductors.

allel conductor-sleeves made of soft copper or other conducting material.

In -the embodiment shown in Figs. 1 to 3 cach conductor-sleeve has integral 'withv and extending from one end thereof, but at opposite ends of the conductor, an enlarged-insulation-sleeve 3, ywhich is of soft meta] adapted to be clamped on the insulation to provide an additional securing means for the conductor. thatthe conductors 4 lead from them at a point midway between the two conductorsleeves 1 and 2, thereby causing the conductor-wires to lead from the connector in alinef ment with one another.

In the embodiment shown in Figs. 4 and 5 the conductor-sleeves 1 and 2 are of known form and the enlarged insulation-sleeves 3a are formed of separate pieces which surround and are secured by solder or otherwise to the ends of both conductor-sleeves. These sleeves 3a lead the conductors from sleeves 1 and 2 in alinement with one another, as in Figs. 1 to 3. i

In `both embodiments the insulationsleeves are provided with slits 5, which permit of the enlargement and contraction of the sleeves toiit different-sized insulations.

The insulation-sleeves not only brace or support the conductor-wires at the weak portion thereof, but they form an additional se-` Connectors made in accordance with my invention make the conductors as strongat the point of joining as at any other point, and when once put in place do not have to be renewed, lasting as long as the conductor will last.l

I desire it to be understood that within the,

scope of the appended claims I may make various changes in the form, the proportions,V
